For us, taxonomy work includes:

Metadata Scheme. Data fields for describing content so that it can be found and used.

Vocabularies. Collections of terms that are used to specify some of the metadata properties.

Relationships between content, fields or terms (hierarchical, equivalence, & associative)

Some vocabularies are big & hierarchical, some are small and flat.

Application Profile. Formal representation of metadata & vocabularies.

Tagging overview

Tagging is better than the words that happen to occur in a piece of content.

All tagging is useful End user tagging Tagging by librarians Automated tagging by OS and algorithms

Content should be tagged throughout its lifecycle, each time the content is handled and used so that it accrues value or its significance is diminished.

What is social tagging?

End user tagging Easy, intuitive tagging interfaces Almost instantaneous feedback

Enables people to tag & re-tag content … in response to seeing their tags in context with other tags.

Emergent categories Resembles open card sort process in which patterns emerge … rather than validating categories using closed card sorts.

What is the semantic web

Making content web-accessible in a format that can be read and used by automated tools, so that people and machines can find, share and integrate information more easily.

Some current examples, especially if they use semantics as the basis for that integration.

Dynamic Web Pages – Content changes in response to different contexts or conditions.

Personalization – Tailoring to a user based on personal details or characteristics they provide.

Mashups – Combining data from more than one source into an integrated application.
